Abstract
A self-expiring band structure is activated upon the contacting of two chemical constituents together. This contacting may be performed by the attachment action of the band or independently thereof. After a time duration has passed, the coaction of the chemical constituents result in a visually perceptible change can alert others to the fact the band has expired. These bands may be both printable, such as by a printer or other machine printing, as well as time-expiring making them a very versatile product that offer heightened security at the price point closer to that of a disposable item because they do not require complex infrastructure for validation.
